A runner loses heat via sweating. This sweat evaporates on the skin which dissipates heat by convection, assuming that humidity is low enough. Heat stroke will occur when the bodies thermoregulation is overwhelmed.
Overwhelming the body (in simplistic terms) may come from excessive environmental heat (running in a hot climate), running too fast or too hard, being dehydrated, a lack of free flowing air that will help cool the body or a lack of water to splash on the body to cool down.

Let’s be clear here, conditions on the trail, fell or mountain don’t necessarily need to be bad for Hypothermia to set in. Running and moving fast creates heat and a runner can generate a great deal of heat in a short space of time. Imagine a scenario where you are moving fast and you have been travelling this way for say 2-hours. You are warm, no hot! You are a little fatigued, hungry, a little dehydrated and then disaster happens… you fall and twist an ankle.
Suddenly moving becomes impossible and you start to cool.
I probably don’t need to elaborate too much here as it’s very easy to see and visualize the scenario that follows.

RUN247 ‘Cavalls del Vent’ 03rd October 2012
Race report: Ian Corless reports after the Ultra Cavalls del Vent – Spain, September 29, 2012
On a day of rain, cold temperatures and intense racing, ultra running and in particular ultra Skyrunning opened a new chapter in our sport with some really competitive racing by ‘the best’ in the world.
Unfortunately the whole experience was somewhat overshadowed by the news on Sunday morning that Teresa Farriol, aged 48, had passed away in the night due to a cardiac arrest brought on by hypothermia. It was hollow faces, dark eyes and tears in the race hotel as elite runners, race organisers and journalists pulled together. The prize presentation was cancelled and was replaced with a one minute silence in the crowded square.

Despite alternative race options available all over the world, many of the worlds best decided to head to Spain and race at the Skyrunning ‘Ultra Cavalls del Vent’, an 84.2km race with 6098m of altitude change.
Kilian Jornet, Dakota Jones, Tony Krupicka, Tofol Castanyer, Miguel Heras, Joe Grant, Philipp Reiter, Anna Frost, Emelie Forsberg, Nuria Picas and Emma Roccaall decided to do battle in what turned out to be an incredibly testing day.
At Refugio Niu de L’Aliga the race format was starting to unfold with Kilian leading the race, followed closely by Tofol and then several minutes back Miguel Heras. Dakota Jones and Philipp Reiter soon came into sight and then Tony Krupicka. Although minutes separated them all, one thing became apparent. It was cold!
Thick mist made visibility difficult and it was biting cold on hands. Kilian seemed in his element running in short sleeves but nearly all the other runners wore jackets. Including Tony!
Emelie Forsberg was the first lady to come into sight. Somewhat of a surprise… not because she didn’t have the ability but because the plan was to ease into her ‘first’ 50 miler. Frosty followed and then a very cool and relaxed looking Nuria Picas.
The cold and constant rain hit the race and the runners hard! Miguel Heras dropped, Tofol had hypothermia, Joe Grant had hypothermia and hundreds more runners had dropped from the race.
Tony Krupicka moved up through the field, moved ahead of Dakota and a format was set. Kilian and Tony swapping the lead and Dakota following.
At Gresolet, Kilian had a two minute lead. As he passed me I asked how he felt? “I am great, it was a little cold but now I am good. I am having fun!”
Tony approached “How you feeling Tony?” “I’m good man, Kilian is just playing with me… all good though!”
Some of the press with me at this point wondered if Tony would win? To be honest, no disrespect to Tony but Kilian seemed in control and was glad of company. Dakota was now some 30 min in arrears with Philipp Reiter in fourth. This order remained until the final climb when Kilian accelerated leaving Tony behind. Kilian crossed the line in a new CR of 8:42:22. Tony crossed the line in second, also beating the old CR too with 8:49:56 and Dakota finished in third in a time of 9:26:25.

Tony was stoked at the finish and rightly so. After the best part of two years of being out of the sport with injuries, his ‘return’ now seems to be confirmed. Speaking of his love for Skyrunning he said on the line “These are the races we want, vertical gain, tough gnarly climbs and altitude. We can’t get this at home, I love it”
Dakota was happy with third, but said he had hoped for better and that he never felt quite on his game!
Emelie Forsberg in the ladies race pushed ahead and at one point had a 15 minute lead, with Frosty and Nuria chasing. However the gap was closed and over the final two hours a battle started. My money was on Nuria, she had told me at ‘Kima’ that this was the race she wanted and I guess it showed. In the latter stages Emelie was dropped and Nuria ran into the finish, victorious in 10:34:42, beating her 2011 winning time by over an hour. Frosty finished in second 10:35:24 and Emelie jumped for joy in 10:39:51.

Frosty said “Everything hurts. I won’t be able to walk tomorrow. I dug deeper that I have ever had to go, I am happy for Nuria and I am happy for me”
Emelie in only her second ultra and first 50 miler was elated. She told me “I felt really good and still do. My legs are not hurting but it was [my] mind… in the latter stages when I had to fight I couldn’t focus but I am super happy”
Cavalls del Vent was an incredible day. It showed us all what is great about our sport. Wonderful courses, great running, new runners showing potential for the future, established runners confirming that they are the best, a return to form for Tony and of course immense comradeship. In the hotel ‘Press Room’ I was surrounded by all of them… Kilian on the sofa chatting, Tony and Dakota on the web, Frosty and Emelie giggling, Philipp and Terry discussing the next time to pose naked. All individual, but all one.
